I am having considerable frustration with updating metadata via scripting.
I have an enterprise geodatabase with many feature datasets. Inside each feature dataset are many feature classes. All feature datasets and feature classes have metadata, which I need to update.
There are 3 sources for my metadata (dynamically-defined items via scripting, synchronized properties, and a template) and I cannot get them to play nice with each other when it comes to displaying the extents of feature classes.
Dynamically-defined items include the fd / fc title, summary, description and tags. Synchronized properties are extents, feature classes, fields, crs, etc. The template contains the credits, contact information (a few times), and other information - stuff that doesn't change regardless of what feature dataset or feature class is being shown.
The most logical flow (in my head) is reflected in my current order of operations:
Import template
Update dynamically-defined items
Synchronize
With that flow, I've tried each of the metadata_sync_option choices; when using 'ALWAYS' everything syncs correctly for feature datasets, and everything syncs correctly EXCEPT Extent for feature classes. How can I get the Extents of feature classes to be properly shown? When I click the Synchronize button everything is perfect, but I need to do this via scripting.
I've tried saving the metadata between steps, I've tried syncing before importing the template, after importing the template.... No joy.
Here is a minimal example of my code
import arcpy
import os
from arcpy import metadata as md
sde_connection = arcpy.GetParameterAsText(0)
metadata_template_path = arcpy.GetParameterAsText(1)
arcpy.env.workspace = sde_connection
fds_list = arcpy.ListDatasets(feature_type='Feature')
for fds in fds_list:
fds_path = os.path.join(sde_connection, fds)
fds_md = md.Metadata(fds_path)
if not fds_md.isReadOnly:
fds_md.importMetadata(metadata_template_path)
# Here I add the metadata that is dynamically generated (title, summary, tags, etc)
fds_md.synchronize(metadata_sync_option='ALWAYS')
fds_md.save()
else:
arcpy.AddWarning(f"Metadata for {fds} is read-only")
arcpy.env.workspace = fds_path
fc_list = []
fc_list = arcpy.ListFeatureClasses()
for fc in fc_list:
fc_path = os.path.join(sde_connection, fds, fc)
fc_md = md.Metadata(fc_path)
if not fc_md.isReadOnly:
fc_md.importMetadata(metadata_template_path)
# Here I add the metadata that is dynamically generated (title, summary, tags, etc)
fds_md.synchronize(metadata_sync_option='ALWAYS')
fc_md.save()
else:
arcpy.AddWarning(f"Metadata for {fds}\{fc} is read-only")
# reset workspace
arcpy.env.workspace = sde_connection
